Example 2 with HeartbeatHandler

use of org.apache.sling.discovery.impl.common.heartbeat.HeartbeatHandler in project sling by apache.

the class VotingHandlerTest method heartbeat.

private void heartbeat(String slingId) throws Exception {
    HeartbeatHandler hh = HeartbeatHandler.testConstructor(new DummySlingSettingsService(slingId), factory, null, null, config, null, votingHandler1);
    OSGiMock.activate(hh);
    HeartbeatHelper.issueClusterLocalHeartbeat(hh);
